KING D. MCQUEEN, 0F ARLINGTON, NEW JERSEY.

METAL-WORKING TOOL.

To all whom it may concern:

Be it known that 1, KING D. MCQUEEN, a citizen of the United States, residing at Arlington. in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Metal- VVorking Tools, of which the following is a specification. v

This invention comprehends certain new and useful improvements in metal working tools and has for its primaryobject to pro vide a tool of this character which will be of simple construction and operation as well as highly efficient in use.

Another object is to provide a device of this character which will be constructed in such manner that it may be readily employed for forming apertures at opposite sides of an opening in metal.

A still further object of this invention is to provide a tool of this character which will be constructed in such manner that the metal penetrating members will be located upon opposite sides of and below the pivot point in the handles by which said penetrating members are carried.

This invention has for a still further object to generally improve tools of this character and construct the same in such man ner that the metal penetrating members may be readily forced through the material and againstthe handle members positiond upon the opposite side of the material and serving to clamp the same and prevent said material from bending during the operation of the tool.

WVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which- Figure 1 is an elevational view of the complete device, showing the preferred form, Fig. 2 is a transverse detail section on the line 2-2 of Fig. 1, Fig. 3 is a longitudinal section on the line 3-3 of Fig. 1, Fig. 4: is a fragmentary elevation of a modified form of the tool, Fig. 5 is a similar view of a still further modified form, Fig. 6 is a bot- Specification of Letters Patent.

tom plan of the form shown in Fig. 4, Fig. 7 is a bottom plan of the form in Fig. 5, Fig. 8 is an elevation of one of the form of tools shown in Fig. 41, removed, and Fig. 9 is an elevation of the semi-spherical head of one of the handles, looking at the inner face thereof.

Referring in detail to the drawings by numerals, 1 designates a pair of handles having enlarged and flattened crossed forward ends 2 terminating in substantially semi-spherical heads 3 having their fiat sides engaged against one another and pivotally connected by means of the pivot member 4: engaged through said heads and forming a pivot point upon which the handles 1 may be rotated, during the operation of the dev1ce.

Projecting from one side of each head 3 and outwardly of the pivot member 1 is an arm 5 having a material penetrating blade 6 positioned along the radially directed edge thereof and the arms 5 preferably extend in opposite directions, whereby when the heads 3 are engaged through an opening in a sheet of metal or the like and the device operated to draw the handles 1 toward one another, said cutting blades 6 will be forced through the material at opposite sides of the opening and form radially directed slots extending from the opening, at diametrically opposite points, the cutting blades 6 and the material cut out by the same being forced against the top walls 7 of the for ward right angled ends of the enlarged portions 2 of the handles 1 directly against the outer face of the material through theopening of which the heads 3 are engaged. It will be understood that slots 8 are preferably formed in the forward endsof the portions 2, as shown in Fig. 1, to receive the blades 6 and the material cut out by the same. Each blade 6 tapers toward its outer end and has its cutting portion extended at a right angle with respect to the remainder of the opposite edge of the blade, as will be readily understood by referring to the drawings. Each blade is also removably positioned in. the recess 13 formed in the inner face of the head 3 by which it is carried, and is provided with a recess of concaved inner end 16 to avoid the pivot member 4. It will therefore be seen that each blade 6 is securely. positioned in the head by which it is carried with the working end thereof projecting beyond the head and resting upon the arm 5 of said head, and outward movement of the blade will be prevented. The blade may be readily removed, however, from its head, after the pivot member 4 has been removed.

It Will bereadily seen that by having the material penetrating blades 6 below or outwardly of the pivot member 4 When penetrating the material, said pivot member is relieved of a large amount of the strain and more pressure may be exerted upon the blades, thereby causing the blades to more readily cut or sever the material and eliminate danger of the blades tearing the material. This will greatly increase the ethcioncy of the device and permit the tool to be readily and easily operated, and it will be readily seen by all familiar with devices of this character, that this tool is especially adapted for use by electricians when setting up electric signs and. forming openings to opposite sides of a larger opening in a. sheet of metal. forming a part of the *asing of the sign, to extend the screws through said casing.

In F d, I have shown a modified form of the device, in which is positioned on the arm 5 projecting from the head 3, a punch (3 projecting radially from the free end of said arm 5, and having an upstanding cylindrical punch proper 6 formed on its extremity to penetrate the material and enter the socket 8 in the opposite right angled. end 7 of the other handle and thereby produce a circular opening in the material to opposite sides of the large opening through which the heads 3 are engaged.

l't'will be understood that each punch 6 is mounted in one of the heads 3 in a manner similar to that described in the preferred form of the device, and owing to the form of the punches 6, the small cir-- cular opening produced by the same in the material will be spaced from the large open mg. p

In the further modified form shown in Fig. 5, each head 3* has an arm 5 projecting therefrom and the heads 3 are connccted by the pivot member 46 the same as in the other two forms of the device. Positioned in a recess 13 in each head 3 is an outwardly tapering and tangentially directed punch 6 having the usual curved or concaved inner end 16 for engagement a ainst the pivot member 4:. It Will be understood that this punch is of substantially the same form as the above described punch With the exception that it is provided with a sharp pointed upstanding punch proper 6'. This sharp pointed punch proper 16, after penetrating the material, enters a conical socket 8"in the right angled end]? of the opposite handle, against which end is pressed the material around the edge of the opening formed by the said opening. d it Will be readily understood from the foregoing, that in all of the forms of this gages in slots or sockets formed in the nardly oi? the head formed thereon. It will also be seen'that the material penetra'ting members may be readily removed or ther be understood that the working parts of this device may be reversed and the material penetrating members carried by the enlarged ends of the handles, if desired. Further, many other minor changes in the details of construction and arrangement of parts may be made Within the scope of the appended. claims without departing from the spirit of the invention or sacrificing any of the advantages thereof.

lVhat is claimed is 1. A device oi the class described comprising crossed members having semi-spherical heads formed at their forward ends with enlarged portions inwardly of said heads, a pivot member engaged through said heads, said enlarged portionshaving reformed therein, an arm carriedby each head with a material penetrating member projecting therefrom and adapted for engagement in the recess of the opposite head.

2. A device of the class prising crossed members having heads formed at their outer encs for engagement through. an opening in a sheet of material, a pivot member engaged through said head, said. crossed members having enlarged portions to opposite sides of the heads with recesses formed therein, and material pone-- described com- Wardly of the pivot point and to the oppo-' site sides thereof and adapted for engagement in the recesses formed in the enlarged portions of said members.

In testimony whereof I athx my signature in presence or" two Witnesses.
